This fella might look very fierce and realistic but we promise he won't bite you! Stick him to a wardrobe or bedroom door for a really original and eyecatching feature. Believe it or not: he starts life as an ordinary A3 sized envelope! First of all, cut off the flap of the envelope. Then you need to fold down the two corners as equally as you can, so that they just pass the half-way mark. Stick the folder corners down with tape. Stuff the envelope with balls of rolled up newspaper. Don't use too much: you need just enough to create a firm body for the shark. This stage can be quite tricky! Using a paper dinner plate, stick it with tape to the larger open end of the filled envelope. Don't worry about the rim that overlaps the edge of the envelope - that comes in very useful later on! Time to make the shark's jaw now. For this, you need another envelope - this time A4 size. As before, cut off the flap. But this time, you need to cut off a bit of the envelope as well. Fold the corners as before, but take the fold right down to the bottom left and top left hand corners. You now need to do another fold. This time, fold over the top right and bottom right corners once again. These help to create a round shape for the jaw. It's now time to join the jaw to the head. Get the position so that it looks right, and then stick it in place with tape. Now, for the tail of the shark you'll need another A3 size envelope. This envelope needs two folds, all the way down to the bottom, as you can see here. Tape each fold in place. Open up the envelope and fill it with more balls of newspaper to give a firmness to the tail. Stick a paper side plate to the larger open end of the envelope, as you did with the head part of the shark. To complete the tail, cut out a couple of fins from cardboard (we used a cereal packet). Slot the tail fin in at the narrow end, and secure it in place, and stick the smaller fin so that it sits upright on the shark's back. It's time to cover both halves of the shark with paper maché. To do this, you need strips of old newspaper. Mix up some PVA glue and water (in equal parts) and paste on the newspaper strips using a brush. Cover both halves of the shark with several layers, and allow to dry overnight. Once it's dry, you can paint it! For inspiration, why not look for pictures of sharks in magazines or on the internet. Or you could use one of our suggested colour schemes! If you use smaller envelopes (A4 and A5 instead of A3 and A4) you could make a smaller shark for sticking onto your stereo, computer or television. Oh and don't forget about the rims of the paper plates: use these to stick your shark onto whatever surface you choose.
